A new 2,2,2-trichloro-N,N׳-bis(2-nitrophenyl)-ethane-1,1-diamine was synthesized by the reaction of 2-nitroaniline in DCM with the chloral formed by distillation of chloral hydrate over concentrated H2SO4. The structure of the title compound was identified by means of FT-IR, 1H NMR, and 13C NMR spectroscopic techniques. The crystal structure of the title compound has also been examined by using X-ray
通过2-硝基苯胺在DCM中与通过水合氯醛蒸馏生成的氯醛反应,合成了新的2,2,2-三氯-N,N׳-双(2-硝基苯基)-乙烷-1,1-二胺浓H 2 SO 4。通过FT-IR,1 H NMR和13 C NMR光谱技术鉴定标题化合物的结构。还使用X射线晶体学技术检查了标题化合物的晶体结构,发现该晶体在单斜晶系和空间群P2 1 / n中具有晶胞参数:a = 7.7075(12)Å,b = 7.7396(10)Å,c = 28.247(4),β= 93.602(5)°,V = 1681.7(4)3,DX = 1.602 Mg的米 - 3,和ž = 4分别。使用密度泛函理论(DFT)方法研究了计算出的标题分子的电子结构性质,例如HOMO-LUMO分析,分子静电势(MEP)图和Mulliken电荷分布。理论上计算出的值显示出化学上坚硬,高动力学稳定性和反应性较低的分子。
